Question

a square + b square =25, ab =12 . Find a-b

Answer 1

AS WE KNOW THAT...

${a}^{2} + {b}^{2} = 25$

And

$a .b = 12$

WITH THIS WE HAVE TO USE THE FORMULAE___

$(a - b)^{2} = {a}^{2} + {b}^{2} - 2ab$

NOW, SOLUTION IS...

$(a - b)^{2} = 25 - 2 \times 12$

$(a - b) ^{2} = 25 - 24$

$(a - b) ^{2} = 1$

$(a - b) = \sqrt{1}$

So,

$(a - b) = 1$
